It’s a great way to spot phonies if you don’t have a lot of time. If you encounter someone who seems to know things but you’re not sure what or how well, check LinkedIn.

If they are flexing as thought leaders, they are bullshit artists and readily ignored.

And the converse is true: If you read something with substance, you can know it is VERY important to them; they're likely literally risking their livelihood to do so.
